The Silesian Piasts were the elder of four lines of the Polish Piast dynasty beginning with Władysław II the Exile (1105–1159), eldest son of Duke Bolesław III of Poland. By Bolesław's testament, Władysław was granted Silesia as his hereditary province and also the Lesser Polish Seniorate Province at Kraków according to the principle of agnatic seniority.

The history of the Silesian Piasts began with the feudal fragmentation of Poland in 1138 following the death of the Polish duke Bolesław III Wrymouth. While the Silesian province and the Kraków seniorate were assigned to Władysław II the Exile, his three younger half–brothers Bolesław IV the Curly, Mieszko III the Old, and Henry of Sandomierz received Masovia, Greater Poland and Sandomierz, respectively, according to the Testament of Boleslaw III.

Władysław soon entered into fierce conflicts with his brothers and the Polish nobility. When in 1146 he attempted to take control of the whole of Poland, he was excomunicated by Archbishop Jakub ze Żnina of Gniezno and his brothers finally drove him into exile. He was received by King Conrad III of Germany, his brother-in-law by Władysław's consort Agnes of Babenberg, at the imperial palace of Altenburg. Silesia and the Seniorate Province came under the control of second-born Bolesław IV the Curly, Duke of Masovia. In the same year King Conrad III attempted to regain power for Władysław, but failed. Not until 1157 Duke Bolesław IV the Curly was defeated in a campaign by Konrads successor Emperor Frederick Barbarossa, however, the "Silesian issue" was not mentioned in the treaty concluded by the rulers, and so Władysław remained in exile. He died in 1159 without returning to Poland.
